Yes. Obviously, it would be pretty hard to feel about someone else the same way you feel about yourself. After all, you can only experience your own experiences firsthand. Not to worry, though, here the word "love" is more about the action of love than the emotion of love. So it's basically another way of saying "treat others the way you would want to be treated". It's a reiteration of "do unto others as you would have them do unto you."
It is possible to come close, but usually, in extreme cases, self-preservation will lead you to save yourself from imminent death BEFORE you save your neighbor. It goes beyond even human nature, to the nature of survival in life forms.
1. Allah Almighty says, "Worship Allah and do not associate anything with Him. Be good to your parents and relatives and to orphans and the very poor, and to neighbours who are related to you and neighbours who are not related to you, and to companions and travellers and your slaves. 2. Ibn 'Umar and 'A'isha reported: "The Messenger of Allah, may Allah bless him and grant him peace, said, 'Jibril continued to advise me to be good to my neighbour until I thought that he would have me make him my heir. 3. Abu Shurayh al-Khuza'i reported that the Prophet, may Allah bless him and grant him peace, said, "Anyone who believes in Allah and the Last Day should be good to his neighbour. Anyone who believes in Allah and the Last Day should honour his guest. Anyone who believes in Allah and the Last Day should speak well or be silent." [Muslim. Al-Bukhari has part of it.
Yes. Which is why Jesus mentioned it as one of the greatest commandments.(Matthew 19:16-19) However, we should really ask ourselves, "HOW do I love my neighbor as myself?" The Bible, throughout, instructs one to exercise love, kindness, generosity, and helpfulness toward one’s neighbor, whether he be merely a dweller nearby, an associate, a companion, an intimate acquaintance, or a friend. The Law commanded: “With justice you should judge your associate [form of ?a·mith?]. . . . You must not hate your brother in your heart. You should by all means reprove your associate, that you may not bear sin along with him . . . and you must love your fellow [form of re?a?] as yourself.” (Le 19:15-18) (In the Greek Septuagint the word re?a? is here translated by the Greek expression ho ple·si?on.) David commends the man who “has not slandered with his tongue. To his companion [form of re?a?] he has done nothing bad, and no reproach has he taken up against his intimate acquaintance [form of qa·rohv?].” (Ps 15:3) Repeated are the injunctions not to do harm to one’s fellowman (re?a?), not even to despise him or to desire anything that belongs to him.—Ex 20:16; De 5:21; 27:24; Pr 14:21.
yes anything is possible with GOD. however our neighbor starts first with our household (family) spouse,sisters,brothers. to those in our community, to our whole human family that extends clear across the globe they're our neighbors just living in a different location Matthew 22:39 jesus said this is the first and greatest command to LOVE YOUR NEIGHBOR AS YOURSELF. just imagine a world with this kind of mentality
